When adding new workspace crates or source directories needed for Rust compilation, update ALL of these:
MANIFEST.in— include Cargo.toml and source files so Python sdist contains themdocker/wheel.Dockerfile— ADD the directory for Python manylinux wheel buildsdocker/wheel-musllinux.Dockerfile— ADD the directory for Python musllinux wheel buildsdocker/gem.Dockerfile— ADD the directory for Ruby gem builds
All three Dockerfiles and the MANIFEST.in must stay in sync with workspace members in the root Cargo.toml.
